However, the wage increase that England has to offer could tempt Mulgrew to move south of the border for the second time in his career.

The versatile player first came to England in 2006 after joining Wolves from Dundee in exchange for Lee Naylor, but after just nine appearances and a loan spell at Southend Mulgrew was back in Scotland with Aberdeen two years later.

Originally coming through the Bhoys’ youth team, Mulgrew left after failing to play a game in 2006, but returned to Celtic four years later in 2010 where he has since made 208 appearances for the club in six years.
